research of PHP for nonprofit sites

Hi,

I hope this thread placed here will help both my project group and the 
evangelist list, itself.

I'm doing research on web site development tools for non-profit or charity 
sites for a senior-level, group, class project on global communications at 
Georgia Tech.

http://www.lcc.gatech.edu/~herrington/classes/gcpsp05/index.html

Our group has to present a proposal on our project, a creative theme 
consisting of our own artist's renderings of results from questionnaires 
around the USA, Sweden and Russia (where our groups are located) in coping 
with the Asian Tsunami Disaster.

The proposal's realized project will be presented on a group made website 
which will contain a forum for users to review the art and suggest other 
ideas or themes.

Our proposal is a multipage (20 to 30 page) ordeal and we've got that due a 
week before the project in mid April.  I will collect as much info as 
possible by early next week, so I can get started with development.

My contribution to the project will be two-fold:

1)    My first addition will be a page or two of collected information on 
the use/benefits of PHP (and maybe other technologies) in nonprofit 
websites.

2)    My second will be the actual development of the site (the backbone 
anyway, we've got students with HTML/Flash experience to make it pretty.) 
I'm very much leaning towards PHP due to obvious benefits (not to mention 
its popularity,) however I need actual proof of concept for my contribution 
to our proposal.

All that being said, could someone provide me some feedback or info on PHP 
technologies in use in the nonprofit/charity communities?  Opinions, links 
to articles, etc. is fair game.  Note, responses may be quoted and 
referenced in my portion of our proposal (note: no emails or contact info 
will be compromised in the references unless previously published via 
article.)

Rest assured, I'll get most of my Google-ing done over the weekend for 'PHP 
charity nonprofit'!

Thanks a lot for the help.
